How we calculated this date
One row per rule, each showing its own input and what it did to the date. A step we could not verify says so instead of resolving itself.
| Step | Input | Date after this step | Confidence |
|---|---|---|---|
| Base term, 20 years from filing | Clock starts Sep 12, 2008, when application 12/209,273, the earliest non-provisional in its chain, was filed (this one was filed Oct 8, 2012) | Sep 12, 2028 | High confidence |
| Continuity chain | Every parent in the chain resolved | no change | High confidence |
| Patent term adjustment | None on file | no change | High confidence |
| Terminal disclaimer cap | Disclaimer resolved from the filed document (refs US 8,116,841, US 8,285,356) | resolves to Sep 12, 2028, no earlier than this term, so no change | Medium confidence |
| Patent term extension | None on file | no change | High confidence |
| Fee events | No fee event states this; the fee state is read from the payments the fee record holds; the fee record shows no payment for this window, and USPTO's status still reads "Patented Case" | no change | Low confidence |
| Reissue | US RE46,926 issued Jul 3, 2018, and this patent's term continues in it (35 U.S.C. 251, 252) | surrendered Jul 3, 2018 | High confidence |
| Surrendered on reissue | The steps above, in order | Jul 3, 2018 | Low confidence |
